Jasmine-ones.

To all whom it may concern: 7 Be it known that I, ARTHUR ATWATER KENT, a citizen of the United States, and a resident of Philadelphia, county of Philadel-f phia, Pennsylvania, have invented certain new and useful Improvements in Measuring- Gages,of which the following is a full, clear,

and exact disclosure.

My invention relates to measuring gages, and particularly to those gages or ullagerods used to ascertain the amount of liquid in a receptacle, and more specifically, to a gage or scale particularly adapted to measure the amount of gasolene, benzin, na htha, naplhthalene, kerosene or similar liquids in a tan As is well known, on account of the shape and location of the gasolene tank of an automobile, it is very difficult to ascertain how much gasolenel there is. at any particular time in the tank and the object of my invention is to provide a gage or scale which will easily and accurately enable the user to tell at any time how many inches or centimeters of tan A further object of my invention is to make a gage of the character above described which will resist and not be affected by the action of gasolene or similar fluids, and to provide it with a surface which will change its a pearance when immersed in gasolene of simi ar fluids so that the immersed part of the gage will present a different appearance from that part which has not been immersed.

A further object of my invention is to provide suitable graduations adjacent the changeable surface so that the depth of the gasolene in the tank can be ascertained at once by the line of demarcation between theimmersed and unimmersed surfaces.

Other objects of my invention will appear in specification and claims below.

In the accompanying drawing forming a part of this specification is illustratedin a perspective view the preferred form of my invention.

A. suitable rod or strip 1, of wood or any other material to which a paint or coating which will resist the action of gasolene or similar fluids, will'adhere, is provided with a stamped, pressed, printed, or painted graduated surface 2, beginning from one end 3, and extending for a suitable. distance toward the opposite end of the strip. I prefer to make the graduated surface 2,0f a light color Specification of Letters Patent. Applicatibn filed March 28, 1908. Serial No. @2399.

g{asolene or similar fluid there is in the" mersed 1n mated May-18, 1909 i v and to form the graduations thereon in acontrastlng color as illustrated in the drawing. Adjacent one side of thegraduated surface of the gage and extending substantially the whole length of [the same, I provide a contrasting surface 4, as by painting a strip or I stripe of contrasting-color. This surface ma be made of a paint or a coating which wi l resist the action of gasolene and 1 preferably make this strip or stripe of amaterial which is normally of a dull appearance, but which will wet with gasolene or similar fluids,

and when wet, will present a shining or Tlns surface 18 one to' glossy appearance. which the gasolene or similar fluid will adhere, but up which the fluid will not creep to any great extent when the stick or-ga e is partly immersed in a body of the liqui I have found that when the surface is painted with dull black lacquer all the above requirements are fulfilled; that is to say, the gasolene or similar fluid, will not attack the lacquer or affect it injuriou'sly in any way, while at the same time the normallyduli black surface will become bright or glossy when'imasolene, thus forming a very sharp clean ine of demarcation between the wet and the unwet surfaces.

To ascertain the amount of gasolene or similar material in the tank, it is merely necessary to immerse the gage in the tank until the end 3, touches the bottom and to then withdraw it. The de th of the gasolene in the tank will lainly s how upon the surface of the gage, tliat part which was immersed presenting a shiningor glossy appearance, and the part not immersed having the dull black appearance. The line of demarcation between these two surfaces will b very plain and the scale or graduations adjacent said surfaces will show exactly how many inches or centimeters of gasolene there are in the tank.

While I have described my invention as particularly adapted for measuring gasolene, 1 do not wish to be construed as being strictly limited to the use to which my invention may be put, since it contemplates the use of anysurface which will not be affected by gasolene, benzin, naphtha, naphthalene, kerosene or similar fluids and which will change in a marked manner its appearance upon being wet with the liquid, and the providing ad acent said surface of a suitable scale for determining the depth of liquid in the receptacle. Nor do I wish to be conposite side, the surface of said gage adjacent strued as limiting to the precise form or arrzamgernent above described since any. em bodiment of the-same 1;

falls wit in the scope of theappended claims;

Having thus described'myinven'tjion,

I claim and desire to protect by Letters Patent of the UnitedStates is:

tending from one end thereof toward the 0psaid scale being coated with a material'which resists the action of gasolene or similar fluids and normally presents a dull ap earance, and

when -wet with the said liquid presents a shining glossy appearance. v

fully within the and pur ose of my invention/sol-long as it;

what

age having a graduated scale ex-' 3.; A-' gage having. a graduated scale extending from one end thereof toward the.oppo'site end and astripe of dull black lacquer ;'adjacent said scale and extending the length thereoAf.

gage having a graduated scale ext-ending engthwise of said gage, and ad3acent sald scale a dark, mattesurface of a material which, when wet with gasolene or simiar fluids, changes to a dark, glossy surface,- whereby, when the gage is partly immersed in said 1i uid, the place to which it has been immerse will plainly show opposite the scale as the line between the matte and .the glossy surface.

In witness whereof I have hereunto set my hand this twentieth day of March A. 1)., 1908.
